Instruments used to predict occurrence of natural disasters

Several systems are used to monitor and predict natural hazards. The following is the list of instruments used to predict the occurrence of various natural disasters:

1. Continuous television and radio broadcasts of severe weather by real-time or near real-time data from meteorological stations and satellite images for prediction of cyclones or floods
2. Seismic instruments are used to measure low-frequency ground motion caused by earthquakes. They detect the seismic waves created by subsurface ruptures and convert ground motions into electronic signals which are suitable for transmission. Instruments that are used to predict earthquakes include the following:
   1. Creepmeters, to warn of movement of the earth's soil;
   2. Global positioning systems, to warn of movement of the earth's crust;
   3. Laser light, to warn of disrupted light beam transmission from one side of a fault line to another;
   4. Magnetometer, to warn of magnetic field changes;
   5. Strainmeters, through the coordinated use of the seismometer and the seismograph, to warn of underground vibrations or shock waves.
3. A drought can be predicted by the consistent lack of rainfall
4. A Tsunami can be predictted using a 'tsunameter'
